This documents the population and household weights for the Promise Neighborhood. We use these weights to calculate estimates from census tract data for the whole Promise Neighborhood.
We have created population based weights for all people within the Promise Neighborhood and for children between the ages of 0 and 17 for both 2010 and 2020 census tracts. Additionally, we created weights for all households within the Promise Neighborhood and households with at least child under the age of 18 for 2010 and 2020 census tracts.
The weights are required because the Promise Neighborhood footprint does not align with census tract boundaries. The weights correct for the percentage of the population or households of each census tract that fall outside the Promise Neighborhood boundaries. They are only valid for creating a combined single estimate for the whole Promise Neighborhood.
The weights are created using Decennial Census Data (2010 and 2020). We summed the populations or households of all census blocks that are inside the Promise Neighborhood for each tract and divived by the total population or household of the tract, creating a weight that accounts for the population distribution within the tract. In the case that a census block was only partially within the Promise Neighborhood, we considered it a part of the Promise Neighborhood if it was at least half in the Promise Neighborhood.
Take the numerical estimate of each tract and multiply it by the weight of that tract. Then sum the resulting product for each tract.
Multiply the numerator and denominator for each estimate by the corresponding tract weight. Sum the numerators and denominators then divide.
Population weights should be used when you are attempting to get an estimate for the something measured at the individual level such as employment. If you are most interested in children, use the population weights for the 0-17 age group instead of the total population.
Household weights should be used when you are attempting to get an estimate for something at that is measured by households or family units, such as household income.
